For developing a Java Web App we need to know basics of Web , Protocols like HTTP(Hyper Text Transfer Protocol), http response/request, Containers, Content Types, Xml , Servers and methods like get and post which are means of transfer of information from one page or side to the other side.
In Simple Words we describe about the HTTP server which is only supported by the web browser we see daily like https://www.google.co.in written over the address bar of our browser. It sends and receives data to and from the server to client.Http Request and Http Response are responsible for all transactions to occur between Client and Server.
